| <p> | |||
| The class name of the Graph2D is <code>vis.Graph2D</code>. | |||
| When constructing a Graph2D, an HTML DOM container must be provided to attach | |||
| the graph to. Optionally, data an options can be provided. | |||
| Data is a vis <code>DataSet</code> or an <code>Array</code>, described in | |||
| section <a href="#Data_Format">Data Format</a>. | |||
| Options is a name-value map in the JSON format. The available options | |||
| are described in section <a href="#Configuration_Options">Configuration Options</a>. | |||
| Groups is a vis <code>DataSet</code> containing groups. The available options and the method of construction | |||
| are described in section <a href="#Group_Options">Data Format</a>. | |||
| </p> | |||
| <pre class="prettyprint lang-js">var graph = new vis.Graph2D(container [, data] [, options] [,groups]);</pre> | |||
| <p> | |||
| Data, options and groups can be set or changed later on using the functions | |||
| <code>Graph2D.setData(data)</code>, <code>Graph2D.setOptions(options)</code> and <code>Graph2D.setGroups(groups)</code>. | |||
| </p> | |||
| <h2 id="Data_Format">Data Format</h2> | |||
| <p> | |||
| Graph2D can load data from an <code>Array</code>, a <code>DataSet</code> or a <code>DataView</code>. | |||
| JSON objects are added to this DataSet by using the <code>add()</code> function. | |||
| Data points must have properties <code>x</code>, <code>y</code>, and <code>z</code>, | |||
| and can optionally have a property <code>style</code> and <code>filter</code>. | |||
| <p> | |||
| Graph2D can be provided with two types of data: | |||
| </p> | |||
| <ul> | |||
| <li><a href="#items">Items</a> containing a set of points to be displayed.</li> | |||
| <li><a href="#groups">Groups</a> containing a set of groups used to group items | |||
| together. All items belonging to a group will be drawn as a single graph.</li> | |||

| <h3 id="Groups">Groups</h3> | |||
| <p> | |||
| Like the items, groups are regular JavaScript Arrays and Objects. | |||
| Using groups, items can be grouped together. | |||
| Items are filtered per group, and displayed as individual graphs. Groups can contain the properties <code>id</code>, | |||
| <code>content</code>, <code>className</code> (optional) and <code>options</code> (optional). | |||
| </p> | |||
| <p> | |||
| Groups can be applied to a timeline using the method <code>setGroups</code>. | |||
| A table with groups can be created like: | |||
| </p> | |||
| <pre class="prettyprint lang-js"> | |||
| var groups = new vis.DataSet(); | |||
| groups.add({ | |||
| id: 1, | |||
| content: 'Group 1' | |||
| // Optional: a field 'className' | |||
| // Optional: options | |||
| }) | |||
| groups.add({ | |||
| // more groups... | |||
| }); | |||
| </pre> | |||
| <p> | |||
| Groups can have the following properties: | |||
| </p> | |||
| <table> | |||
| <tr> | |||
| <th>Name</th> | |||

| </table> | |||
| <h2 id="Configuration_Options">Configuration Options</h2> | |||
| <h3 id="graph2dOptions">Graph2D Options</h3> | |||
| Options can be used to customize the Graph2D to your purposes. These options can be passed to the Graph2D object either in | |||
| the constructor, or by the <code>setOptions</code> function. | |||
| <pre class="prettyprint lang-js"> | |||

| <h2>Graph2D | Basic Example</h2> | |||
| <div style="width:700px; font-size:14px; text-align: justify;"> | |||
| This example shows the most basic functionality of the vis.js Graph2D module. An array or a vis.Dataset can be used as input. | |||
| In the following examples we'll explore the options Graph2D offest for customization. This example uses all default settings. | |||
| There are 10 predefined styles that will be cycled through automatically when you add different groups. Alternatively you can | |||
| create your own styling. | |||
| <br /><br /> | |||
| Graph2D is built upon the framework of the newly refactored timeline. A lot of the timeline options will also apply to Graph2D. | |||
| In these examples however, we will focus on what's new in Graph2D! | |||

| dataAxis (y-axis) icons have been enabled as well. These icons are generated automatically from the CSS | |||
| styling of the graphs. Finally, we've used the option from Timeline where we draw the x-axis (time-axis) on top. | |||
| <br /><br /> | |||
| The <code>align</code> option can be used to align the bar at the center of the datapoint or on the left or right side of it. | |||

| <h2>Graph2D | Groups Example</h2> | |||
| <div style="width:700px; font-size:14px; text-align: justify;"> | |||
| This example shows the groups functionality within Graph2D. This works in the same way as it does in Timeline, | |||
| We have however simplified the constructor to accept groups as well to shorten the code. These groups are the | |||
| method used in Graph2D to define individual graphs. These groups can be given an individual class as well as all the | |||
| styling options you can supply to Graph2D! This example, as well as the ones that follow will showcase a few different usages | |||
| of these options. <br /> <br /> | |||
| This example also introduces the automatically generated legend. The icons are automatically generated and the label is the | |||
| content as you define it in the groups. If you have datapoints that are not part of a group, a default group is created with the label: 'default'. | |||
| In this example, the setting <code>defaultGroup</code> is used to rename the default group to 'ungrouped'. | |||

| Finally, the legend is manually positioned. Both the left and right axis | |||
| have their own legend. If one of the axis is unused, the legend is not shown. The options for the legend have been split | |||
| in a <code>left</code> and a <code>right</code> segment. Since this example shows the right axis, the right legend is configured. | |||

| This example shows the some of the graphs outlined on the right side using the <code>yAxisOrientation</code> option within the groups. | |||
| We also show a few more custom styles for the graphs. Finally, the legend is manually positioned. Both the left and right axis | |||
| have their own legend. If one of the axis is unused, the legend is not shown. The options for the legend have been split | |||
| in a <code>left</code> and a <code>right</code> segment. The default position of the left axis has been changed. | |||

| <h2>Graph2D | Interpolation</h2> | |||
| <div style="width:700px; font-size:14px; text-align: justify;"> | |||
| The Graph2D makes use of <a href="http://en.wikipedia.org/wiki/Centripetal_Catmull%E2%80%93Rom_spline" target="_blank">Catmull-Rom spline interpolation</a>. | |||
| The user can configure these per group, or globally. In this example we show all 4 possiblities. The differences are in the parametrization of | |||
| the curves. The options are <code>uniform</code>, <code>chordal</code> and <code>centripetal</code>. Alternatively you can disable the Catmull-Rom interpolation and | |||
| a linear interpolation will be used. The <code>centripetal</code> parametrization produces the best result (no self intersection, yet follows the line closely) and is therefore the default setting. | |||
| <br /><br /> | |||
| For both the <code>centripetal</code> and <code>chordal</code> parametrization, the distances between the points have to be calculated and this makes these methods computationally intensive | |||
| if there are very many points. The <code>uniform</code> parametrization still has to do transformations, though it does not have to calculate the distance between point. Finally, the | |||
| linear interpolation is the fastest method. For more on the Catmull-Rom method, <a href="http://www.cemyuksel.com/research/catmullrom_param/catmullrom.pdf" target="_blank">C. Yuksel et al. have an interesting paper titled ″On the parametrization of Catmull-Rom Curves″</a>. | |||

| <h2>Graph2D | Scrolling and Sorting</h2> | |||
| <div style="width:700px; font-size:14px; text-align: justify;"> | |||
| You can determine the height of the Graph2D seperately from the height of the frame. If the <code>graphHeight</code> | |||
| is defined, and the <code>height</code> is not, the frame will auto-scale to accommodate the graphHeight. If the <code>height</code> | |||
| is defined as well, the user can scroll up and down vertically as well as horizontally to view the graph. | |||
| <br /><br /> | |||
| Vertical scrolling is planned, though not yet available. The graphHeight also does not conform if only the <code>height</code> is defined. | |||
| <br /><br /> | |||
| You can manually disable the automatic sorting of the datapoints by using the <code>sort</code> option. However, doing so does reduce the optimization | |||
| of the drawing so if you have a lot of points, keep <code>sort</code> turned on for the best results. | |||

| This example is a test of the performance of the Graph2D. Select the amount of datapoints you want to plot and press draw. | |||
| You can choose between the style of the points as well as the interpolation method. This can only be toggled with the buttons. | |||
| The interpolation options may not look different for this dataset but you can see their effects clearly in example 7. | |||
| <br /><br /> | |||
| Linear interpolation and no points are the settings that will render quickest. By default, graph2D will downsample when there are more | |||
| than 1 point per pixel. This can be manually disabled at the cost of performance by using the <code>sampling</code> option. | |||

| * provided start Date, end Date, and minimumStep. | |||
| * | |||
| * If minimumStep is provided, the step size is chosen as close as possible | |||

| * Alternatively, you can set a scale by hand. | |||
| * After creation, you can initialize the class by executing first(). Then you | |||
| * can iterate from the start date to the end date via next(). You can check if | |||
| * the end date is reached with the function hasNext(). After each step, you can | |||
| * retrieve the current date via getCurrent(). | |||
